Key characteristics and recent progress of high speed Photodetector
With the development of science and technology, the application of high speed Photodetector (optical detection module) in many fields is more and more extensive. This paper will introduce a 10G high-speed Photodetector (optical detection module) that integrates a high-speed response avalanche photodiode (APD) and a low noise amplifier, has a single mode/multi-mode fiber coupled input, SMA connector output, and has high gain, high sensitivity, AC coupled output, and flat gain.
The module uses the InGaAs APD detector with a spectral range of 1100~1650nm, which is suitable for high-speed optical fiber transmission systems and high-speed optical pulse detection. In the field of optical communication, the sensitivity and speed of photodetectors are crucial performance indicators. The high sensitivity of the module reaches -25dBm and the saturation optical power is 0dBm, ensuring reliable data transmission under low optical power conditions.
In addition, the module also integrates a preamplifier and booster circuit, which can effectively reduce noise and improve the signal to noise ratio. The AC coupled output can reduce the influence of DC component and improve the quality of signal. The gain flatness characteristic enables the module to have a stable gain at multiple wavelengths, further optimizing the signal quality.
In the field of application, the module is mainly used in high-speed pulse detection, high-speed space optical communication and high-speed optical fiber communication. With the development of technology, the demand in these fields is also increasing. Therefore, the development and application of this module is of great significance.
The module’s performance and application make it one of the most advanced photodetectors on the market today. It has the characteristics of high performance, high stability and high reliability, and can meet the application needs of different fields. In the future development, with the continuous progress of technology and the continuous expansion of application fields, the module will be more widely used and promoted.
